“…For absorption, materials must have an electric dipole or magnetic dipole to interact with the EM fields. Materials with a high dielectric constant such as BaTiO 3 have high electric dipoles, whereas materials with high magnetic permeability, such as a Fe 2 O 3 and Fe 3 O 4 , have high magnetic dipoles. − As already mentioned, traditionally, copper, aluminum, and other conductive metals were the first choice for EMI shielding materials due to their capability for effective reflection of electromagnetic (EM) radiation. For reflecting the EM waves, the materials must have free movable charge carriers since free movable charge carriers can interact with an electric field and reflect the EM waves.…”

Advancements in technology and widespread usage of electronic equipment have led to a vast hike in electromagnetic pollution such as electromagnetic interference (EMI). This has resulted in major concerns regarding human health and improper functioning of electronic devices. Therefore, high-performance EMI shielding materials are necessary to ensure human well-being and protect systems in domestic, civil, or military applications. Earlier, metals and alloys of metals served as EMI shielding materials. But due to their heavy weight, low corrosion resistance, and advancements in miniaturization of electronic devices, currently, metals have only restricted applications in EMI shielding. Thus, flexible, lightweight, and high-performance EMI shielding materials assume great significance. Polymer composites have emerged as a better alternative to EMI shielding materials because of their light weight, corrosion resistance, and ease of fabrication. This article reviews the important literature on electrospun polymer composite fibers for EMI shielding applications. Fabrication methods and different types of fillers and their influence on EMI shielding properties are discussed in detail. The article tries to highlight the huge potential of the electrospinning technique toward the development of specialty materials for EMI shielding.

“…However, the strategy of incorporating Fe 3 O 4 MNPs in biomaterial scaffolds may be hindered by shielding effect and poor thermal conductivity of matrix, decreasing the magnetothermal efficiency of Fe 3 O 4 MNPs. [116] To address this problem, Zhang et al proposed to fabricate a 3D-printed -TCP bioceramic scaffold modified with Fe 3 O 4 MNPs/GO nanocomposite layers ( -TCP-Fe-GO), which could improve thermal conductivity and magnetothermalefficiency for eliminating tumor cells due to the exis-tence of magnetothermal agent Fe 3 O 4 MNPs and thermal conductor GO (Figure 7A). [36] Interestingly, magnetic heating curves of Figure 7B exhibit that the maximum temperature of -TCP-Fe-GO scaffolds could be increased to 80°C under an AMF, which could be regulated by adjusting magnetic field intensity or Fe 3 O 4 amount.…”

Bone tumors bring great pain to patients, along with a high disability rate and high mortality. Several therapeutic strategies have been applied to treat bone tumors, such as chemotherapy, radiotherapy, and surgical resection. However, these strategies have intrinsic drawbacks, such as the serious side effects of chemotherapy or the necessary reconstructive surgery of surgical resection. To help develop more satisfactory bone tumor treatment strategies, biomaterial scaffolds have been proposed. Biomaterial scaffolds are often applied for repairing bone defects after surgical resection due to their biocompatibility, osteoinductivity, and osteoconductivity as well as excellent physicochemical properties. Simultaneously, the function of bone tumor therapy offers biomaterial scaffolds to eliminate residual tumor cells, thus avoiding tumor recurrence. This review summarizes recent advances in biomaterial scaffolds which are combined with chemotherapy or hyperthermia therapy for treating bone tumors and further bone regeneration. Moreover, the progress in synergistic therapy of bone tumors based on biomaterial scaffolds is also discussed. This review aims to inspire researchers to develop novel fabrication or functionalization strategies for constructing multifunctional biomaterial scaffolds with anti-tumor properties.
